Over the past six months my water called RT has developed a pronounce squeak from exhaust valve . My local BMW dealer has told me is not covered by warranty as it is part of the exhaust and for the sum of £60 greased it for me whilst it was having its third service last month. The valve lasted for a ride home and then started sweaking again, however yesterday squeak became very noticeable during a long ride from Dorset to the west Welsh coast and back. This morning I took the valve cover off and squirted copious amounts of WD-40 on it all seem fine for about an hour and then the squeak reappeared. Has anybody managed to sort the problem out or does it matter if it squeaks.
If I take the silencer off is the valve exposed to let me put something like copper slip or a graphite based grease or even a graphite grease spray on the shaft and bearing surfaces . I have also enclosed two photos . I would like it sorted as I'm off to Portugal next month for 15 days on it.
Thanks in advance
